----------------------------------------------

             Summary: Failure in star expansion on struct fields
                 Key: IMPALA-5994
                 URL: https://issues.apache.org/jira/browse/IMPALA-5994
             Project: IMPALA
          Issue Type: Bug
          Components: Catalog
    Affects Versions: Impala 2.10.0
            Reporter: Thomas Tauber-Marshall
            Priority: Blocker


If a table is created externally in hive with struct field names containing upper case letters, selecting the fields of the struct with a '*' fails with the error 'IllegalStateException: Slot paths should be lower case'

Repro:
{noformat}
hive> create table case_test (s struct<FIELD:int>);

impala> invalidate metadata;
impala> select s.* from case_test;
{noformat}
